Additional Info

This code the following types of intra-peritoneal infections:
- Generalized ("regular") acute peritonitis
- Spontaneous Bacterial Peritonitis (SBP) -- this is an entity that occurs in people with pre-existing ascites
- Abscesses that aren't included in the Alternative codes listed below, thus included in this code are:
  - "intra-abdominal abscess" (intraabdominal abscess) or "abdominal abscess" or "intra-pelvic abscess" (intrapelvic abscess) or "pelvic abscess" that don't have any additional information about where it originated (e.g. as below, abscesses related to diverticulitis or appendicitis, and a few others, have their own specific codes)
- Retroperitoneal abscess
This code EXCLUDES the specific causes/types of abdominal or pelvic infections as listed below
Often abdominal paracentesis is done to test the fluid for WBC and cultures
A diagnosis of SBP is usually made by finding polymorphonuclear cell (PMN, also referred to as neutrophils) count in the ascitic fluid is ≥250 (or 500) cells/mm3, and secondary causes of peritonitis are excluded
- Culture results might be negative if antibiotics were started before the sample was taken; you can still code this with a pathogen of Infectious organism, unknown
Peritonitis

Alternate ICD10s to consider coding instead or in addition

Intra-abdominal infection codes:
Abscess of intestine Anus or rectum, abscess Appendicitis, with or without rupture or peritonitis Diverticulitis, small or large intestine (diverticular disease with perforation or abscess) Internal female reproductive organs and adnexa NOS, inflammatory or infectious disorder Psoas abscess Retroperitoneal abscess

Disorder of peritoneum, NOS

Candidate Combined ICD10 codes

Infections

Infections in ICD10 have combined coding requirements for some of their pathogens. Any that have antibiotic resistances would store those as Combined ICD10 codes as well. If the infection is acquired in the hospital, see Nosocomial infection, NOS. See Lab and culture reports for confirmation and details about tests. See Infections in ICD10 for more general info.

Attribution of infections

cirrhosis codes:
Hepatopulmonary syndrome, NOS Liver cirrhosis, NOS Liver cirrhosis, alcoholic Primary Biliary Cirrhosis (PBC)

if coding cirrhosis also code cause of cirrhosis if known
